Nat: an 'absurd' price may be a seller signalling that he is not interested in selling unless the offer is so right that he'd be a fool to reject it. I do that sometimes. I know Dan McKee (hi Dan) is unabashed about his doing so.
As much as I hate to agree with Jake
on anything, he's right about the credit card thing. I made a sale recently to someone who was willing to meet my price because he could use a CC to fund it. Not everyone has even cash flow.
